Key takeaways
- Roots can absorb salt and dehydrate; salt spray can burn foliage, especially on evergreens.
- A coffee mug of salt, about 12 ounces, covers about 1,000 square feet.
- Keep trees and shrubs at least 3 feet from salted walks and 7 feet from roads when planting.
- Avoid piling salted snow on shrubs.
The studies and recommendations here come from a Minnesota university because we have not found a Nevada fact sheet on the subject. Northern Nevada has less salt use than the Midwest but the plant biology is the same.
How does salt hurt trees?
University of Minnesota Extension explains that roots can absorb salt, which causes dehydration, and that salt spray can burn foliage, especially on evergreens. Sodium also makes clay soil expand and compact, reducing water infiltration and root growth. Symptoms include dried, brown needles and leaves, loss of foliage, buds and branches, and premature plant death.
Use less
- A coffee mug of salt (about 12 ounces) is enough for about 1,000 square feet, per the Extension.
- Spread it evenly, about 3 inches between grains.
- Sweep up loose salt from dry surfaces.
- Shovel first. The less ice that bonds, the less you need.
Alternatives, and their limits
| Product | Notes (University of Minnesota Extension) |
|---|---|
| Sand | Adds traction but does not melt ice; can block drainage systems. |
| Beet brine | Lowers the temperature at which salt works and reduces environmental impact; its sugars can deplete oxygen in nearby waterways. |
| Alfalfa meal | Provides traction and melts ice; its nitrogen can contaminate waterways. |
Where snow goes
Avoid depositing snow onto nearby shrubs, because it may contain salt or break branches. Pile it on lawn or open ground away from trunks. If you hire a snow contractor, tell them which beds and trees to avoid and walk the site together.
Planting and replacing
The Extension recommends keeping trees and shrubs at least 3 feet from driveways and walks where salt is applied, and at least 7 feet from roadways where salt spray may occur. It advises against planting evergreens along surfaces where deicing salts are used. We do not plant trees. If a tree is declining along a salted walk, a certified arborist can look at it and help you decide between pruning and removal.
How can you tell salt is hurting a tree?
Browning needles on the side of an evergreen facing a road or walk, dieback of twigs, scorched leaf edges and slow decline along a salted strip all point to salt. Other things cause the same symptoms, including drought stress, which is common here. Water is scarce on the valley floors, with annual precipitation of about 4 to 10 inches by NOAA normals, so a stressed tree can be suffering from several things at once. A certified arborist can look at the tree and say what is likely.
A simple winter routine
Shovel early and often, spread a thin even layer only where you need traction, sweep up what is left, and pile snow on open ground away from trunks and shrubs. Plan your planting beds at least 3 feet from salted walks. These habits protect trees and cost little.
Our salting
We salt as part of our snow and ice removal. If your trees are near a walk or lot, tell us when you book so we can adjust. Call 775.232.8243 for a free estimate.
